BOBBIN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 645,&17, dated March13, 1900.

A lic tion mea December11,1899. seri'No. 739391. (No model.)

To all whom it may cncern:

Be it known that I, GEORGE A. CLARK, a citizen of the United States, anda resident of Lowell, county of Middlesex, and State of Massachusetts,have invented an Improvement in Bobbin-I-Iolders, of which the followingdescription, in connection with the acconpanying drawings, is aspecification, like -letters on the drawings representing like bobbinont of the holder and then toss it into a box' or down a chute.

By means of this invention the spent bobbin is ejected from the re'ar ofthe bobbinlolder as the fresh bobbin is inserted, the ejected bobbinfalling'into a chute or other device suitably attached to the spooler todirect the bobbin to a box or other convenient or desirable collectingdevice, saving much hand labor and facilitating the operation' of theapparatus. i

Figure 1 is a cross-'sectional View of a portion of a spooling-machine,showing a bobbin-holder embodying one form of my invention with adischarge-chute and receptacle for spent bobbins. Fig; 2 is an enlargedside elevation of one of the bobbin-holders with a full bobbin therein.Fig. 3 is a rear end elevation of the bobbin-holder, showing the closureor gate for the discharge-opening in normal position; and Fig. 4 is asimilar View showing the gate open to permit the exit of a spent bobbin.

Referring to Fig. 1, the frame A drivingdrum A for the spindles' a, onwhich are mounted the spools A to receive the thread from the bobbins,the rod B, upon which the bobbin-holders are secured, and thethreadguides t may be and are all of well-known or nsnal Construction. ii

Referring more particularly to Figs. 2, 3, and 4, the holder is shown asconprising, essentially, an upturned overhanging arm A,

having at its lower end a clamp A', provided with aset-screw, a bracketb extended from the clamp having attached thereto a rest orpan d for thebobbin C, all substantially as in United States Patent No. 575,929,granted January 26, 1897, swinging guards g being supported on 'theforwardly-extended .part of the arm A'. I have herein shown thelate'ally-i enlarged npright portion A of the arm at the rear of therest d and which forms a backstop forthe bobbin as cut away to form adischarge-opening cflthrougl which a spent bobbinis ejectcd. i v

As shown in Fig. 2, the bobbin-head c is maintained outrof alinenentwiththe opening a by the yarn wound upon the bobbin; but as the y'arn is unw'onnd the bobbin comes nearer and nearer to the pan d and the spent orsubstantially-empty bobbin will bein position to pass through saidopening.

In order to prevent thepremature discharge of the bobbin, I provide aclosure or gate m for the opening, pivotally mountcd by a pin m' in earsa on the rear of the back-stop at one side of the opening a an arm mextended substantially at right a'ngles to the gate having its 'endenlarged o'r weighted, as at m As shown, the fulcrum m' is obliqu'e orinclined to the vertical, so that the weighted arm, heavier than thegate, will operate to shut the latter and normally close the opening,the weight of the bobbin being insnfcient of itself to open the gate.Now-'supposing the bobbin has 'been unwonnd it is in proper position tobe ejected, and the operative simply puts the fresh bobbin in from thefront, its head butting against the tip of the empty one and pnshing itthrough the opening, the gate m being swung to one side by the spentbobbin. As soon as the latter is ejected the gate swings shut, while thehead of the fresh bobbin engages the face of the back-stop 0nt ofalinement with the dischargeopening. The operative is thns relieved ofwith adischarge-openng for aspent'bobbin,

one hand operation which now eonsunes considerable time, amounting to agreat deal in the aggregate, as several thousand may have to be handledin the course of a day.

I have shown in Fig. 1 a trough or chute L, with its upper end beneaththe dischargeopenings of the several bobbin-holders, so that the ejectedbobbins fall into the chute and are directed to a box L or otherconvenient receptacle for collecting them. The closing movement of thegate is stopped by env gagement of a part thereof with the backstopadjacent the fulcrun, as at a Fig. 3.

My invention is not restricted -to the precse Construction andarrangenent shown, as

the same may be modified or rearranged in various particulars Withoutdeparting from the spirit and scope of my inventicn.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, isa 1. In a bobbin-holder, a rest for the bobbin, anda back-stop having a discharge-opening for a spent bobbin, the unWonndbobbin obe- .ing maintained by the yarn thereupon out of alinenent Withthe opening.

2. In a bobbin-holder, a rest for the bobbin, aback-stop having adischarge-opening for a spent bobbin, the yarn maintaining a bobbinopening, and a swinging gate to normally 40 out of alinement with the'opening till unvvound, and a movable closure for theopening. e

3. In a bobbin-holder, a rest for the bobbin, an upturned, overhangingarm forming a back-stop at the real' of the rest and provided theunwound bobbin being maintained by the yarn 'thereupon out 'of.alinenent With the close said discharge-opening 4. In a bobbin-holder,a rest for the bobbin,

v a back-stol) havin a dischar e-o enin for a b b a spent bobbin, theyarn maintaining a bobbin out of alinement with the opening tillnnwcund, and a pivotally-mounted, normallyclosed gate for said opening i5. In a bobbin holder, a rest or pan, and

a back-stop having a discharge-opening at the i rear end of the rest,and a self-shutting gate to normallyclose said opening.

8. In a bobbin holder, a rest for the bobbin, an npturned back-stop atthe rear end thereof having a discharge-opening for a 'spent bobbin, agate obliqnely fulcruned adjacent and to close the opening, 'and aweightedvarn on the gate, to normally maintain the latter shut;

9. 'A spooling-nachine having a series of bobbin.-holders each providedWith a bobbinrest and a back-'stop having a dscharge-open ing for a'spent bobbin, and a' chute located below the hobbin-holdersand havingits open top arranged to receive spent bobbins When ,ejected through thedischarge-openings of the holders. r v

10. A bobbin-holder having a rest for the bobbin, and means topermitejection of the spent bobbin When moved longitndinally upon therest toward the back of the latter, i

11. A Vbobbin-holder having a rest for the bobbin, a discharge-outletfor the passage of the spent bobbin whenengaged and moved longitndinallyby an-incoming fresh bobbim and means to' 'prevent accidental ejectionof vabobbin. t i s p In testimony whereof Ihavesigned my' 'name to thisspeeification in the presence of two subscribing witnesses.
